Continuous extension of a rational measure family whose positive increments are supported on the corresponding trace intervals.

  1. structure OAI.SLEExactGauge.RationalTraceIncrements line 21

    Source documentation

    This is the positive-increment and interval-support assertion used in the pathwise extension. Local applications restrict all measures to one compact set, making the terminal measure finite.

    Source documentation

    The rational family has an all-real-time regular extension, continuous against every compact continuous test. It is dominated by the same finite terminal measure, and agrees exactly at every rational time.
